A.12.4.2 UK Compliance Statements

The E1 Interface is approved in the UK for direct connection to PTO-provided circuits
operating at data rates up to 2.4Mbit/s.
The E1 Interface comprises a combination of single or dual WAN cards, CEPT modules, and
connector panels as listed in the UK approval documentation.
The approved CEPT configuration options are shown below.
The Interface Card is also listed in the approval documentation and provides a direct metallic
path between the CEPT module and appropriate Connector Panel.
The power required by the host and the total of all adapter cards installed within the host
environment, together with any auxiliary apparatus, shall not exceed the power specification
of the host apparatus.
Refer to Appendix A. System Specifications in this System Reference Guide for details on E1
interface power requirements.
It is essential when other option cards are introduced which use or generate a hazardous
voltage, the minimum creepages and clearances are maintained. Suitable user protection to
ensure compliance with EN 60950 should be present on the card. A hazardous voltage is one
that exceeds 42.2V peak AC or 60VDC. If you have any doubt, seek advice from a competent
installation engineer before installing other adapters into the host equipment.
The equipment must be installed such that with the exception of the connections to the host,
clearance and creepage distances are maintained between the card and any other assemblies
that use or generate a voltage. Large clearance and creepage distance applies where the local
environment is subject to conductive pollution or dry non-conductive pollution which could
